16 Claims.

This invention relates to certain improvements in containers forlipsticks, eyebrow pencils and similar soft pasty cosmeti a type ofcontainer is supported in a carrier an enclosed casing to then withdrawninto the cs, and particularly to in which the cosmetic stick which ismoved from expose the stick for use and casing and covered by a capmember, this type of dispenser being generally known as a swivel-typelipstick container.

One of the inherent faults of the above type of lipstick containers isthat frequently in packing the container for shipment, or carrying thesame around in a handbag, or

idly playing with the same, the members composing the container areliable to be accidentally each other with the result forced into contactwith rotated in relation to that the cosmetic is the inside of the cap,

creating disgurement and soiling of working parts and deforming theshaped end of the cosmetic, to the annoyance of the user, and to theprejudice of the market.

It is, therefore, the main object of this invention to provide a simplemeans intentional movement of the cosmetic stick by which the uncasingis eiectually prevented.

It is a further object to provide a cosmetic container of the abovenature in which means are provided for interlocking propelling means ofthe when assembled thereon, vide for such interlocking readily appliedto a standard or the rotatable cosmetic casing with the cover andespecially to promeans which may be stock lipstick with the minimum ofchanges and parts.

With these and other objects in view, the invention consists in certainnovel features of construction, combinations and arrangements of parts,as will be more fully disclosed in connection with the accompanyingdrawing and as set forthv in the annexed claims,

In the drawing:

Figure 1 is a partial side elevation and partial lipstick containerembodying of this invention, and showing the their normal assembledlocked position. 2 is a longitudinal sectional view through covershowing them in with the locking eleview of the inside shell of theelements of the AFigure 4 is a detailed perspective view of an insertshell, which is adapted to be inserted within.tlie cover member, antures of the locking means.

d discloses other ieaf (Cl. 20G-56) Figure 5 shows a side elevation viewof a modified construction, portion of said view being broken away tobetter show the locking feature.

Figure 6 shows fragmentary separated views of cover and containermembers showing a further 5 modification of the form disclosed in Figure5.

Figure l is a fragmentary sectional View of a hinged cover swivellipstick container showing the locking feature embodied therein.

Referring now to the drawing in which like nu- 10 merals refer tocorresponding parts throughout the several views: the numeral I0 refersgenerally to a dispensing container comprising an outside tubular casingII and inside shell I2 rotatably mounted therewithin. Disposed betweenthe 15 casing II and shell I2 and adapted to be retained and carried bythe outside easing II is a spring sleeve I3 having a helical groove orslot I4 extending from end to end thereof.

The base or lower end of the inside shell I2 is 20 provided with anintegral head I5 which is adapted to extend beyond the outside diameterof the outside shell II. The head i5 is preferably provided with aknurled surface as best shown in Figures 1 and 3 to assist inmanipulating the 25 same, but it is to be understood that the head I5could be made as well of any polygonal shape to omit the knurled portionwithin the scope of the invention. The upper end of the inside shell I2has a portion indicated by the numeral I6 30 formed outwardly in amanner to be more specifically pointed out later, this deformed portionI6 for the present serving to rotatably interconnect the inside shell I2with combined outside shell IIl and sleeve I3, and adapted to engage S5against the upper annular edge of the spring sleeve I3 as a thrustbearing.

Mounted to slide within the inside shell I2 is a v cosmetic stickcarrier inthe form of a cup I'I in which is held a cosmetic stick I8.The inside 0 shell I2 is formed with a longitudinal slot I9`extendingsubstantially the entire length of said shell. Within, adapted toslidably engage the slot I9, there is provided a head 20 of a pin 2secured to the cup I'I as best shown in Figure 2. 5 The pin 2l, ifdesired, may project a substantial distance within the cup to beembedded within the material of the cosmetic stick as a better means forholding the stick I8 within the cup I'I, The head 20 of the pin 2l isadapted to pro- 50 ject beyond the slot I9 and engage within the helicalslot IG of the sleeve I5 previously mentioned, and as will be evident,the merc rotation of the inside shell I2 relative to the outside casingII through the manual operating of the head must protrude in use.

' which isprovided with I5 will positively project and retract thecosmetic stick I8 carried by the cup I1.

'Ihe forward end of the outer shell II is rounded inwardly as at 22 tolprovide for a smooth surface surrounding an opening 23 in the end of theoutside casing through which the stick Il The container I0, when thecosmetic is Withdrawn, is adapted to be closed by a closure cap 24 asshown in Figures 1 and 2, a crowned closing end 25 and is designed totelescope over the entire length of the outside shell II. Up to thispoint the construction disclosed is old in the art of lipstickcontainers and forms no part of the present invention except as used incombination with the interlocking feature hereinafter disclosed.

In accordance with this invention there is provided means whereby theinside shell I2 and complementary operating head I5 are interlockedagainst rotation within the casing II by the mere assembling of the cap24 upon the container I 0, thus preventing accidental longitudinalmovement of the stick carrying cup I1. While the specific constructioneffecting this locking feature may be somewhat varied as shown by `themodifications herein, the preferred and simplest construction isdisclosed in Figures 1 to 4 inclusive. Thus, there is provided a steppedcup-like insert shell 26 comprising an upper larger cylindrical portion21 and a lower smaller portion 28. The smaller portion 28 is providedwith 'a series of scallop-like longitudinal projections or utes 29,which assume in transverse cross section a sinuous annular ring.

The insert shell 26, shown in Figures l and 2, is adapted to be disposedin the upper end of the closing cap 24 adjacent to crowned end 25. Theouter diameter of the cylindrical section 21 of the insert shell 26 issuch, relative to the inside diameter of the closure cap 24; that saidinsert 4shell 26 is assembled into its permanent position preferably bya drive or force fit to assure a rigid and non-rotatable connectionbetween the parts. The insert shell 26 is originally formed with a crownor base end closing the smaller section 28 of said shell, and conjoinedby a noticeable radius that naturally provides for a chamfered or roundbevel-like portion 30 which Ais adapted to merge smoothly into the lowerends of each of the flutes 29, (see Figure 4). Subsequently, the base ofthis shell may be pierced out to provide for an opening 3l to allow forsuitable clearance for a new cosmetic stick in case its lengtlh shouldcause it to extend upwardly therewithin.

'I'he upper outwardly formed portionl I6 of the inside shell I2previously mentioned is like- Wise formed with a series of correspondinglongitudinal scallop-like projections or flutes 32 presenting a sinuousring (see Figure 3) which permits interengagement with the flutes 29 ofthe insert shell 26 in the cover 24.

Now when the cover 24 is assembled upon the casing lil its full length,the flutes 29 of the insert shell 26 are adapted to slidably interiitwith the corresponding flutes 32 in the expanded portion I 6 of theinside shell I2 in an interlocking manner; if, perchance, the iiutes 32are not in proper alinement with the flutes 22 of the insert shell 26,they will be automatically forced into such alinement, coincident withthe telescoping of the cov'er 24 and the container l0, by reason of thechamfer 30 on the end of the iiutes 29 .previously mentioned. 'I'hus itwill be evident that through this interlocking feature when the and wellknown i cover 24 is upon the casing I0 it will not be possible toactuate any movement of the carrier cup I1.

In Figure 5 there is shown a modified form of the interlocking featurewherein the insert shell 28 is omitted from the cover 24a, and in placeinside shell I2a adjacent to the head I 5a. The

upper end of the section 36 may be likewise chamfered, as at 31, tofacilitate the full assembly of the cover 24a.

In case it is objectionable to place visible flutes or teeth on thelower end of the cap 24a in Figure 5, this may be avoided by aconstruction disclosed in Figure 6, wherein the lower end of the cap 24his provided with an inner attached collar 38 having the interlockingiiutes 39 positioned within the inner end of the cover 24b adjacent theopen end. The collar 38 may be made secure to the cover 24hby being spunover and forming an attaching bead 40 around the lower annular end ofsaid cover 24h. Obviously the construction of the inside shell may beformed the same as in the modification of Figure 5 as shown by thefragmentary view in Figure 6 except' for the relative diameter of theenlarged section 36a. v

In Figure 7 there is shown the interlocking feature applied to alipstick container having a hinged closure cap. Herein is' disclosed anouter casing IIC having a projecting circumferential rib 4I adjacent theupper open end. A relatively narrow cap 42 is attached to the rib part4I of the casing by a hinge 43, a construction well known in the art. Aninsert shell 44 is axed within the interior of the cap as by soldering,and said shell 44 is formed with suitable projecting elements similar tothose disclosed in the preferred form of the invention, and designed tohave interlocking engagement with the correspondingly formed ring 45integral with the upper end of the inside shell I 2c. Obviously theclosing of the hinged cap 42 effects the desired locking feature.

Before concluding this specification, attention is called to the factthat one of the outstanding desiderata of this interlocking feature forlipstick containers resides in the simplicity of construction, whereinsaid interlocking feature can be applied to the several types of stocklipstick containers disclosed without the necessity of changing theestablished set-up in tools or operations making such stock lipsticks,it being only necessary to slightly reform one of the parts and add anew shell to the cover.

While this invention has been shown and described in several forms,itwill be understood that other changes and variations may be made in thespecific constructions shown and described without departing from thescope of the invention as defined in the appended claims.
